Development process
For those familiar with my models. The truck cabin is more or less a straight forward designed as always; only changes are a new front-grille, more realistic inner cabin floor, new sleeping bed with night-lights and a new roof-skirt at both sides. Of course the folding sleeping bed and coffee machine is still there.
To support both LEGO® Powered-Up and Power Functions, 2 different chassis types needed to be designed; both are included in the Building Instructions.
As I designed the model both in a LEGO® Powered-Up and Power Functions system, I am able to compare them. Regarding the motors (XL, L and M) I noticed no difference in force, only slightly faster driving in the Powered-Up version. Using the servo function in the Powered-Up version is a little 'shaky' when steering from a Smartphone is being performed. However, I experienced to use the 'big' single sliders in the Powered-Up application as it appears these can be controlled more precisely.
The significant Powered-Up break-through is of course the Bluetooth operation; especially outdoor. At the other hand, although programming is really fun (hazard lights), it has a steep learning curve for those not familiar with code-block building.
Last but not least, not having LEGO® Powered-Up extension wires is a real miss in the portfolio.
However, the 3rd party market provides solutions for this, see picture more 'down below'.
